No. To is a distance.
The distance to the star is usually measured by parallax.
There is no other way to determine To than to set To = -d/c
That you change the unit from ly to y doesn't change the fact
that -To⋅c = √(x² + y² + z²). To is redundant.
No, To is an abstract time.
It is the time that an observer placed very far away and at an equal distance from A and B would measure between the reciprocal anisochrony of A and B.
This is the time that physicists use to calculate the time taken for light to come from Tau Ceti to us, and they say To=12 years.
But no one on Earth measures this time. It is an abstract time supposedly measured by a distant observer placed at an equal distance between A and B.
In reality, in the "plane of present terrestrial time" the sending of the photon and the reception of the phton are simultaneous.
This is what is so difficult for physicists to understand, and it is partly what blocks them in a quantity of reasoning that leads to paradoxes that they no longer know how to resolve.
To=-AB/c
t=0
